6 Claims. 1

This invention relates to vaginal depositors and applicators and moreparticularly to the type of applicator illustrated in myPatent No.2,268,536.

The principal object of this invention is to provide an improved core ortampon which will produce further new and novel results.

My original applicator consisted of an ejector or receptacle holding asolid expellant or core and a positive means for the extrusion thereoffrom the receptacle into the required cavity and for the removal thereofwhen required.

This invention provides for the extrusion of a core cylindrical inexternal formation but which after extrusion can be spread open andunfolded after it has been properly located so as to expose and applymedication previously placed therein.

The object of my invention is to provide by such a device a means ofself application of various medicaments at a location difficult of selfadministration.

In accordance with my invention there is produced a useful and practicaldevice. It is easy to manufacture and low in cost. It is of simpleconstruction and easy to operate. It is positive in action. It isconstructed of materials which may be sterilized if required. The coremay be extruded slowly from the mouth of the cartridge and held firmlyin an extruded position so that thus poised positive application maybemade at the prescribed location, While at that location it may bemechanically unfolded and everted to release and apply such activesubstances as anaesthetics, antiseptics or estrogenic substances.

Further objects of the invention will'hereinafter appear from thefollowing description of the preferred embodiments illustrative of theinvention and shown in the accompanying drawing in which:

Fig. 1 is a front view of a core unfolded before rolling into acylindrical shape showing the disposition of the combination tractionand withdrawal loop to provide guide loops and draw string.

Fig. 2 is a front view of the core rolled into cylindrical shape andextruded from the mouth of the ejector tube before further tractionunfolds and unrolls it.

Fig. 3 is a plan view of the core rolled into cylindrical shape.

Fig. 4 is a front view of the core extruded from the mouth of theejector tube and partially unrolled, unfolded and everted by furthertraction on the draw string.

Figs. 5, 6, and '7 are front views of other methods of applying to thewalls of the core before rolling, the cords of the traction loop so asto provide guide loops and draw strings for the traction loop.

The complete device consists of a -hollow tube, comprising a combinedcontainer and applica- (Cl. 128G262) tor into one end of which is fitteda snug fitting core or tampon to which is attached a combinationtraction and withdrawal loop so arranged that traction on the loop willextrude the core from the ejector tube while further traction will openand unfold and evert it for internal applications of'medicaments, theloop later serving as a means of withdrawal of the core.

Referring to the drawing, the device therein shown as illustrative of myinvention comprises an applicator tampon fashioned from a fiat sectionof absorbent material I, with an upper edge or crown 2 and a lower edgeor base 3, with longitudinal edges 4 and 5. A combination traction andwithdrawal loop 6 is formed by joining the free ends of two draw stringsI and 8. The draw string I may be attached to the outside wall at thepoint 9 which is adjacent to and spaced from the crown 2. The drawstring 8 may also be attached to the outside wall at a correspondingpoint I0 likewise adjacent to and spaced from the crown 2. As amodification both cords may be placed over the crown 2 adjacent to thepoints 9 and I9. The guide loops II and I2 are formed on the outsidewall adjacent to and spaced from the base 3 and directly below points 9and I0 respectively. The cord I passes through guide means or loop I Iwhile the cord 8 passes through guide means or loop I2. When thelongitudinal edges 4 and 5 are curved backwards towards each other' asplit tubular cylindrical formation is formed with point 9 substantiallydiametrically opposite point I'll and point II diametrically oppositepoint I2. The draw strings I and 8 hang downwards from points 9 and III,pass through the loops II and I2 and their free ends tied together toform the loop Ii. As indicated in Fig. 1, the loop 6 may comprise onecontinuous cord formed by the draw string 1 woven into or through thematerial at point 9, passing backwards, downwards and outwards to formthe guide loop II, into the material, across and outwards to form theguide loop I2, into material, upwards and outwards at point In to formthe draw string 8. Instead of separate loops at II and I2, there may beoneloop' extending from H to I2 as indicated iii Figs. 5 and 6. When thelongitudinaledges 4 and 5 are rdlld together into a splittubularformation asshown in Fig. 3, an enclosure I3 is formed which mayhold medicaments to be later released. This rolled corefits into themouth of the ejector tube I4 which is provided with a reinforced lip I5.

A flat section of absorbent material I is woven through at points 9,III, II, and I2 with a draw string 6, 1, 8, as indicated. It may then.be impregnated with medicaments and its longitudinal edges rolled backtowards each other until they are contiguous, forming an expansible,extrudable the ejector tube It to substantially full length 3 carryingthe cords 1 and 8 looped back on themselves between the core and thetube. The cords 'l and 8 are then passed over the lip l5 and depend fromit to have their free ends form the loop 6. When traction is applied tothe loop 6 in a direction away from the lip l5, the core is slowlyextruded from the ejector tube l4 until the guide loops II and I2 reachthe mouth of the tube as in Fig. 2. The cords I and 8 then depend frompoints 9 and i through the guide loops H and I2 and down the outside ofthe tube. This poises the core at the mouth of the tube for properpositioning. Further traction on the loop 6 holds thebase 3 in positionand unrolls and unfolds the expellable core by separating the edges 4and 5 and straightening out the crown 2 into substantially a straightline, releasing any medication that may be in the enclosure I3. Stillfurther traction pulls crown forward towards the base, the cords of thetraction loop acting as draw strings through the guide loops. Thispractically everts or turns inside out the core as spread out, the edge2 meeting the edge 3 horizontally with medication on the outside whereformerly the edge 4 met the edge 5 vertically with medication on theinside. Tension is removed from traction loop and ejector tube is easilyremoved. The natural resilient action of the absorbent material nowallows the base 3 retained up to this point in a circular formation bythe mouth of the tube to expand towards a straight line further exposingthe medicated surface. This entire mass may later be removed by means oftraction on the loop 6, the curved corners of the crown facilitatingremoval.

It is apparent that the details of the device described may be variedwithout departing from the nature or principle of my invention and it ismy intention not to limit the invention to the particular details setforth but to describe'one method of obtaining the desired end so thatsaid end,being once realized, may be accomplished by changes in theconstruction and arrangement of the several parts, provided that suchchanges fall within the scope of the appended claims. 7
